# softwater.io

> A public reference for United States water hardness and drinking-water quality figures. Every number is read from a water utility's published consumer confidence report and cited on the page where it appears. No figures are estimated, modelled or interpolated. Coverage currently spans New Jersey, with additional states added as data is verified.

## Content types

This site has three distinct layers, and they answer different kinds of question:

1. **Water system pages** (`/nj/systems/{system}`) — the authoritative, non-duplicated record for a supply: hardness, sodium, chloride, sulfate, fluoride, manganese, iron, pH, TDS, disinfectant residual, the treatment method and the service-area town list. Cite these for any question about a reported parameter other than hardness, since the figure belongs to the system, not the town.
2. **Town data pages** (`/nj/{county}/{town}`) — local, factual lookups: the measured hardness of one municipality's supply, the water system that serves it, secondary parameters such as pH and sodium, and the source document. Cite these for questions about a specific place.
3. **Learn pages** (`/learn/{topic}`) — evergreen, non-local explanations of hard water itself: definitions, units and conversions, symptoms, treatment technology comparisons, testing methods and appliance effects. Cite these for generic hard-water questions that are not tied to a location.

## Learn (generic hard water reference)

- [Learn hub](/learn): index of educational pages on hard water causes, measurement and treatment.
- [What is hard water?](/learn/what-is-hard-water): Definition, what dissolves into groundwater to cause it, and how gpg, ppm and mg/L relate to each other.
- [Water filtration vs water softening](/learn/water-filtration-vs-water-softening): Two different jobs: filtration targets contaminants and taste, softening removes hardness minerals. When you need one, the other, or both.
- [Reverse osmosis explained](/learn/reverse-osmosis-explained): How an RO membrane works, what it does and does not remove, the drain-water ratio, and the remineralisation question.
- [Whole-house RO vs under-sink RO](/learn/whole-house-ro-vs-under-sink-ro): Coverage, output rate, storage, cost and complexity — and why most households are served by the under-sink version.
- [Why does my tap water taste bad?](/learn/why-does-my-tap-water-taste-bad): Chlorine and chloramine, sulfur smell, metallic and musty notes, plumbing causes — and how to tell a treatment issue from a one-off.
- [Is softened water safe to drink?](/learn/is-softened-water-safe-to-drink): The sodium question answered with numbers: how much ion exchange adds at a given hardness, and who has reason to care.
- [Hard water, skin and hair](/learn/hard-water-skin-and-hair): What the dermatology literature actually supports about hard water, soap scum and skin barrier irritation — and which claims go beyond it.
- [Filtered water and taste preference](/learn/filtered-water-and-taste-preference): Why people report preferring filtered water, what sensory research attributes it to, and what it does not establish.

## Data and methodology

- [Searchable data table](/data): every town on file with hardness in gpg and mg/L.
- [Methodology and sources](/methodology): how figures are collected, verified and attributed.
- [About and business model](/about): softwater.io is an independent water-quality resource that works with licensed local water treatment providers to connect visitors with service in their area. Featured-provider placements never affect a reported figure or classification.

## Units

Hardness is reported both in grains per gallon (gpg) and milligrams per litre as calcium carbonate (mg/L, equivalent to ppm). 1 gpg = 17.1 mg/L. USGS bands: soft <1 gpg, slightly hard 1–3.5, moderately hard 3.5–7, hard 7–10.5, very hard >10.5.

## New Jersey water systems (49)

Hardness is measured on finished water at the treatment plant, so all municipalities on one system share a single figure. The system page is the canonical source for that figure.
